Brief Introduction
Just as its name implies, high frequency is that the frequency is relatively high, generally refers
to the frequency of >=300 MHz (i.e. wave length <=1m), that is, the usual radio frequency band.
The electromagnetic wave of frequency >=1GHz is called microwave.
Typical frequencies for wireless applications:
* Current mobile: 0.9GHz - 2GHz
* 3G systems: 2.5GHz
* Bluetooth: 2.5GHz
* GPS: 12.6GHz
* LMDS: 24GHz and 40GHz
* Automotive: 77GHz
Market: RFID, Wireless communications, base station and antenna, amplifier, military products,
consumer electronics.
High frequency printed circuit board or microwave PCB refers to the printed circuit board made
on the high frequency (microwave) substrate copper clad plate. The common types are: Double
-sided board, multilayer board and mixed structure.
Mixed structure includes high performance special substrate, PP sheet + ordinary performance
board and PP sheet mixed pressing board; high frequency substrate + ordinary FR4 substrate;
high frequency substrate + metal base etc.
PCB Case: 2 Layer High Frequency PCB Built on 20 mil
RO4350B With Immersion Gold
(PCB's are custom-made products, the picture and parameters shown are just for reference)
General description
This is a type of high frequency PCB built on 20mil RO4350B substrate with Tg 280°C for the
application of UHF Radio. It's 0.6 mm thick with black silkscreen substrate and immersion gold
on pads. The base material is from Rogers supplying single up board. They're fabricated per
IPC 6012 Class 2 using supplied Gerber data. Each 50 boards are packed for shipment.
Features and benefits
Excellent dimensional stability;
Low water absorbability influences dielectric constant and dielectric loss less at damp;
The dielectric constant (DK) is low and stable, so the signal transmission is good without
delay;
SMT process is resistant to reflow soldering, resistant to rework due to gold pads;
Comprehensive equipment management and maintenance and process control;
Thermal stress test, reliability test, insulation resistance test and ionic contamination test;
1-10 pieces are offered;
RoHS materials;
Diversified shipping methods.
Application
Modular oscilloscope, Antenna combiner, Analogue transmitter, Power amplifier
